Abstract

La présente invention a trait à un système de démarrage de turbine à gaz (100) qui comprend un arbre (30, 34) couplant un compresseur (22, 24) et une turbine (28, 32). Un boîtier annulaire (118) sétend circonférentiellement autour de larbre (30, 34) de manière que le boîtier annulaire (118) définisse un compartiment (102). Une bride (122) sétend radialement vers lextérieur à partir du boîtier annulaire (118) pour fixer ce dernier à une paroi fixe (116). Un démarreur (152) est positionné dans le compartiment (102). Un collet (120) est couplé de manière rotative au boîtier annulaire (118) et est couplé sélectivement au démarreur (152). Le collet (120) comprend une surface radialement interne (164) comportant une pluralité de cannelures (166) destinées à venir en prise avec larbre (30, 34). Le démarreur (152), lorsquil est activé, fait tourner le collet (120), ce qui fait tourner larbre (30, 34) pour faire démarrer une turbine à gaz (10).
